Water heating manufacturer Rinnai has entered its products into a head-to-head challenge against super league rugby team Widnes Vikings.

Rinnai, an official sponsor of the Widnes Vikings rugby league club, put its Infinity water heaters head-to-head with the players in a contest of Man vs Machine, played out over YouTube.

The challenges laid down to the Vikings were:

'Rinnai water heaters can produce 1,000+ litres of water from a unit weighing just 31kg. How quickly can a professional rugby player pull this weight against his peers?'

Rinnai water heaters are accurate to 1°c of the chosen set point, but how accurate are the Vikings?

After putting the team members through their paces in two gruelling playoffs, Gil Dudson, Vikings front row, headed the leader board for the club overall on both tasks – pulling 180 kgs in 10.93 seconds (most stored hot water systems are considerably heavier than Rinnai's sprightly 31kg) and kicking the oval ball at a Rinnai unit to test accuracy – and the Rinnai units won hands down for specifiers, installers and end users alike.

Chris Goggin of Rinnai said: "Relentless durability is a key feature of the Rinnai range of gas fired water heaters and that is the message we are aiming to get across by pairing with Widnes Vikings for this YouTube campaign. This is a brand-heavy, mass-media campaign targeted at increasing market awareness, albeit in a light-hearted manner."

"The videos have been viewed online more than 21,000 times to date. We are encouraging our customers to use the Rinnai/Vikings YouTube videos in their marketing, too, to raise awareness of the Rinnai brand to their clients."
